Add On Developer's Forum

The Add On Developer's Forum is for add-on's to flight simulator that do not fall into the category of a/c, scenery, repaints or mesh. This forum is established to provide authors an area to gather, share ideas, code, and get feedback from users. If you are a developer of other add-ons to MSFS, this forum is for you.

  1. Hello AVSIM community, I've just released v0.2.2 of Aviator Ledger, a browser-based airline career simulator currently in free beta. I'd welcome feedback from experienced simmers and anyone with real-world aviation knowledge. Website: aviatorledger.com — no account required, runs in your browser. This update focused on a complete overhaul of the private aviation charter business system: — Operating certificate fees scaling with fleet size (Part 135 style, $2K-$50K/month) — Crew management with annual raises, seniority bonuses, morale tracking, and attrition — Type rating enforcement on crew aircraft assignments — Reputation system (0-100) gating …

You can ask the AI to execute the commands or simply do the check where you only have to say if it's done or not. Whatever you add, the AI will sea…

    Please let me know if this isnt the right place to post this. Im having an issue with the Dynamic Lod Mod whereas I download it, it works fine a couple of times then Sim Connect won't light up. I shut down everything including the sim then go to start it up again and it won't show on my screen and doesnt show up in the sim so there is no way to tell its working or nake changes to it but it shows in the Task Manager as running so yeah weird. Does anyone have any suggestions? It happens everytime. Dont know how to insert a pic here

  7. I have only the bgl and textures. I know how to add a 3d model, but it doesnt show in game, just with developer mode, assets missing or the like. How should the file structure be like and how to save and build package with correct assets. Lets see: i have *.bgl and textures folder, how to proceed?

  9. I'm not sure if this has been brought up, and general searches just bring up so much extra 'fluff' nowhere related to the topic. But after all this time, AIG still points many of the manual files to the site unitedtrafficteam.com. It's now and has been for a while, just a false search engine, one of those 'this domain is for sale' sites, most likely used by 'less than ethical' folks to trick you into visiting similar sites. I have found one thread on the net from a supposed admin that they were trying to get permission to put files on said site. But nothing further. I've tried numerous times to register on the AIG forum but only get as far as the message that an…

    Good morning, I understand that Flightbeam recently changed their forums. So I created a new account and it says "Looks like you don't have access. This category is only available to select members." I have an issue with one of their products and I can't seem to get an answer. I've tried to contact them several days ago and I haven't heard back. Has anyone else encountered this issue where you can't access their new forums?

  14. Hello! I wrote a couple of addons to scratch a few itches I had with the main MSFS UI, such as: Favorites Tags Notes Auto control preset switching Custom location saving ++ The videos below are a bit long winded (ha!) but go into most of the detail. If you want to cut to the chase just check out the benefit/feature list on the website links below: Aircraft Manager for MSFS Location Manager for MSFS Free lite versions available as well. Any question, fire away! Happy flying!

  15. Just thought I would share a little side project I've been working on! I've always done some modelling but only for myself. This one hopefully will be released for everyone soon! (payware).

  17. Hello! I want to have a poke at creating a skydiving/parachuting addon, which is a little different from powered aircraft. Some of the issues were discussed here: https://forums.flightsimulator.com/t/paid-parachuting-addon-i-know-there-is-an-fsx-freeware/552750/5 I have a lot of real world experience in it, as well as development, but finding it difficult to find good resources on getting started with doing a custom WASM flight model, which is what is needed for this type of "aircraft" scenario(s). eg: (from link above) Skydiving/parachuting is unique in the sense that the flight model geometry of the human body/parachute morphs into many possible states…

    I am getting an error PackageToolConfig version is too low in file (got 0, expected 2). Please update the XML file to correct version. How do I update the XML file to the correct version? I have looked all over and cannot figure it out. All I am trying to do is edit trees around an airport so that its more realistic, but the first stage of building the package is throwing me errors that I do not understand.

    My Blender is a new version 3.4.1 I'm new to exporting in Blender so I expected trouble. My project was a House model I wanted to add to the sim, as I was having trouble with this I tried a simple box in two LODs. I used the basic colour with no textures and got the same error as the house. the error is: This is the last line: TypeError: Converting py args to operator properties: : keyword :export_displacement" unrecognized. I'm wondering if the MSFS multi exporter is compatible with Blender version 3.4.1 Does anyone know or what the error is?

  21. Hi, I'm trying to develop a SimConnect program to monitor AI Traffic. I'm able to do this successfully for some AI Traffic SimVars (like Airspeed) using SimConnect_AddToDataDefinition, SimConnect_RequestDataOnSimObject, etc.., but I cannot see the AI Traffic State (STATE_ENROUTE_AS_FILED, STATE_WAIT_INIT_CONFIRM, etc.). The name of this variable is given online as "AI TRAFFIC STATE", but I get "EXCEPTION_NAME_UNRECOGNIZED" when I try to request it. I wonder have Asobo changed the name of this to something else? Thanks, John

  23. Hello, I’ve just published the first version of a project which allows remote access to basically all the Gauge API functions available to a standalone WASM module. It consists of, yes, yet another, WASM module, but also includes full client-side implementation libraries for both C++ and C#/.NET. It is completely open source and licensed under L/GPL v3. (I hope this is a good place to post, since it’s not really an add-on for the general public but is geared specifically towards other programmers as a tool. And I hate promoting anything, but not sure how else other devs would find out about it. I hope someone finds it useful.) A WASM module-based Server a…

    Hi, im a developer and this would be my first addon. Just wondered if any others developers would be able to tell me if this is possible please? I was thinking about reading coordinates of current location of aircraft and putting it in a Google map/bing maps or other free maps sharing this location over the local network so it can be accessed by other devices. Is this possible before I look into it please? cheers
